TROGLODYTES. 103not far from Riobamba i. Mr. Buckley's recent collections from the same country alsocontained examples. From Ecuador it has since been traced southwards to Peru ^ andBolivia*, and northwards to the Colombian State of Antioquia 3, and now to CostaRica.It seems to enjoy a considerable range in altitude, as Eraser's specimens were obtaineda little under 10,000 feet above the sea, Salmon's in Antioquia at a much lower eleva¬tion, and some of Mr. Buckley's at Puna Island, almost at the sea-level. Salmon foundits nest, which he describes as placed in a hole m a waU or bank, or any convenientspot, being made of soft blades of grass with an entrance at the side. The eggs arewhite, spotted with small red spots, but not nearly so profusely as those of T. aedon. 6. Troglodytes brunneicoUis.Troglodytes brunneicoUis, Scl. P. Z.

G.^). This is a weU-marked Wren belonging to the group containmg T. aedon and itsallies, being of about the size of that species, and having a tail of similar proportions.In colour, however, it somewhat recalls the North-American T. hyenmlAs, its longer tail,larger size, and clear fulvous colour of the under surface distinguishing it from thatspecies. We suspect, however, that the first specimens obtained by M. SaUe atEl Jacale i", and called T. hyemalis by Mr. Sclater, were really T. brunndcollis. Thesebirds have now been lost sight of and cannot be traced; but as they are the origin ofthe only reference to T. hyemalis in Mexico, we think that they were very likely mis¬named. The first recognition of this Wren was based upon specimens obtained in December1857 at La Parada by M. Boucard. This viUage is in the highlands of Oaxaca, andstands at an elevation of about 10,000 feet above the sea. T. brunneicoUis has sincebeen traced to many other parts of Southern Mexico, being, according to Prof. Sumichrast,one of the commonest species of the alpine region of Vera Cruz at an elevation of from5000 feet to 6500 feet above the sea ^
